The shock has several meanings, but doctors, for medical purposes, define it as a condition in which the flow of blood through the body suddenly becomes inadequate, and vital organs remain unresponsive. This can happen from one of the following three reasons: first, heartbeat can drastically weaken so that the heart does not pump out enough blood – for example, after coronary thrombosis (cardiogenic shock); secondly, after the loss of blood or some other body fluid – for example due to broken arteries, severe burns, long diarrhea or perforated ulcer – the volume of blood can be dangerously reduced (hypovolemic shock); third, the blood vessel diameter can be increased as a consequence, for example, of a strong allergic reaction or infection – that there is a relative lack of blood although the actual amount has not diminished (anaphylactic or septic shock). There are other factors, but these are the main physical causes.
If a shock develops, the state of the body begins to get worse. Because of insufficient blood flow to the brain, the brain remains oxygen-free; it has a detrimental effect on the nerves, which control the diameter of the blood vessels, so that the blood vessels become too widened and decomposed; blood pressure continues to fall, and so it continues. From this condition the body cannot recover from itself alone. Therefore, treatment should be immediately accessed.
Symptoms that can occur without warning include sweating, numbness, nausea, shortness of breath, rapid pulse and pale, cold and damp skin. Blood pressure drops rapidly to values that are far lower than acceptable. Since there is no blood supply to the blood, a person in shock becomes sleepy, disturbed, and may not be conscious.
Although people in the shock often die, we do not have statistical data because a cause of death is recorded as a disturbance or injury due to which man has come into the state of shock. In addition to the victims of traffic accidents, the greatest threat of shock is to people with internal bleeding of any cause, with strong poisoning of the blood or those who suffer from some types of heart or severe lung diseases, such as asthma.
Untreated shock leads to death because the body can not recover by itself. Even if the treatment starts immediately, the shock can lead to brain and kidney damage.
The outcomes of healing from hypovolemic shock are pretty good if the main cause is quickly removed, but other types of shock can be fatal.
What to do?
If someone near you is in shock – the condition is immediately recognized – immediately go to the doctor. People in shock can not help themselves.
A man in shock should be taken to a hospital, preferably an intensive care unit. Special equipment is used in this department, for example a continuous blood pressure monitor and a continuous ECG recording apparatus; Such devices give immediate information on the condition of a person in shock. The main tasks of the doctor are to assess the depth of the shock and to determine the root cause.
In most cases, it is primarily necessary to establish normal blood pressure so that body organs get enough blood to survive. The doctor pulls the thin tube into the vein, usually on the upper arm, and connects that tube to the bottle with plasma or blood. This increases the volume of blood and thus the blood pressure. If the brain is not yet damaged, it will respond by re-establishing control over the tone and diameter of the blood vessels. In many cases, the doctor pays special attention to the kidneys to prevent kidney failure. Diuretics will stimulate the kidneys to produce more urine to endure until they recover from oxygen deficiency.
If a normal blood pressure is set by emergency intervention, treatment of the root cause will depend on the severity of the condition and its cause. For example, an ulcer that bleeds much may be operated, or high-dose antibiotics may be injected into the bloodstream in order to counteract severe infections. The prospects for full recover depend partly on the root cause and partly on the speed of urgent medical intervention in critical minutes when the body is in a state of shock.
